{"product_id":"runtru-air-handler-a5ahc","title":"RunTru A5AHC Air Handler — 1.5 to 5 Ton, Multi-Position, R-454B","description":"\u003ch3\u003eHalf the system, and half the rating\u003c\/h3\u003e\n\u003cp\u003eAn air handler is not an accessory to the unit outside. It holds the indoor coil, the blower and the filter, and the efficiency printed on your AHRI certificate belongs to the \u003cem\u003epair\u003c\/em\u003e rather than to the condenser. Put a mismatched coil behind a good condenser and the system will never reach the number it was sold on. The A5AHC exists so the RunTru A5AC and A5HP condensers have an indoor half they are actually certified with.\u003c\/p\u003e\n\n\u003ch3\u003eMulti-position, which is what solves the closet problem\u003c\/h3\u003e\n\u003cp\u003eUpflow, downflow or horizontal from a single cabinet. This matters more than it sounds, because the building dictates the orientation and the catalog does not: a Florida garage or attic usually wants horizontal, a hallway closet wants upflow, a unit sitting over a crawlspace may want downflow. One model covers all three, so nobody discovers on installation day that the wrong configuration was ordered.\u003c\/p\u003e\n\n\u003ch3\u003eThe blower is what you actually feel\u003c\/h3\u003e\n\u003cp\u003eCapacity gets the attention, but airflow is what the room experiences. A blower that can run longer at a lower speed pulls more moisture out of the air than one that blasts and shuts off, and in the Southeast humidity is at least half of what \"comfortable\" means. It is also the difference between a system you can hear from the next room and one you cannot.\u003c\/p\u003e\n\n\u003ch3\u003eAll-aluminum coil\u003c\/h3\u003e\n\u003cp\u003eThe coil is all-aluminum rather than copper tube with aluminum fins. Mixing the two metals in a humid or salt-air environment invites galvanic corrosion, which is the most common reason an indoor coil leaks refrigerant years before the rest of the system is worn out. A single-metal coil removes that failure mode entirely.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to order alongside it\u003c\/h3\u003e\n\u003cp\u003eIf you are pairing this with a heat pump, supplemental heat lives \u003cem\u003ehere\u003c\/em\u003e, not in the outdoor unit — it is an electric heat kit that slots into the air handler and is sized in kilowatts for your climate and house. It is sold separately and listed in our accessories; your installer should specify the kW rating. This is the single most commonly forgotten item on a heat pump order.\u003c\/p\u003e\n\n\u003ch3\u003eMatching it correctly\u003c\/h3\u003e\n\u003cp\u003eDesigned to match the RunTru A5AC and A5HP outdoor units. Check the AHRI reference number published on the listing for the exact combination you intend to install — and if you would rather not assemble the match yourself, the complete systems are listed as single items.\u003c\/p\u003e","brand":"RunTru by Trane","offers":[{"title":"1.5 – 2 Ton","offer_id":49310249582851,"sku":"A5AHC002A1B30A","price":1550.0,"currency_code":"USD","in_stock":true},{"title":"1.5 – 2.5 Ton","offer_id":49310249615619,"sku":"A5AHC003A1B30A","price":1625.0,"currency_code":"USD","in_stock":true},{"title":"2 – 3 Ton","offer_id":49310249648387,"sku":"A5AHC004A1B30A","price":1685.0,"currency_code":"USD","in_stock":true},{"title":"3 – 4 Ton (A5AHC005)","offer_id":49310249681155,"sku":"A5AHC005A1D30A","price":1845.0,"currency_code":"USD","in_stock":true},{"title":"3 – 4 Ton (A5AHC006)","offer_id":49310249713923,"sku":"A5AHC006A1D30A","price":1910.0,"currency_code":"USD","in_stock":true},{"title":"3.5 – 5 Ton","offer_id":49310249746691,"sku":"A5AHC007A1D30A","price":2145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/3278\/5667\/files\/hf_20260829_204047_fdab8ffc-44a6-4423-8961-798fd69719b2.png?v=1788036189","url":"https:\/\/hvacsupplypro.com\/products\/runtru-air-handler-a5ahc","provider":"HVAC Supply Pro","version":"1.0","type":"link"}
